SELECTING THE INSTALLATION LOCATION 2-1 INDOOR UNIT · Where airflow is not blocked. · Where cool air spreads over the entire room. · Maximum refrigerant piping length between indoor unit and outdoor unit is 30 m and the difference of height of both units is 15 m. · Rigid wall or ceiling without vibration. · Where it is not exposed to direct sunshine. · Where easily drained. · At a distance 1 m or more away from your TV and radio. Operation of the air conditioner interferes with radio or TV reception in areas where reception is weak. An amplifier may be required for the affected device. · In a distance as far as possible from fluorescent and incandescent lights (so the infrared remote control can operate the air conditioner normally). · Where the air filter can be removed and replaced easily. Warning I Do not install it by yourself (customer). Incomplete installation could cause injury due to fire, electric shock, the unit falling or leakage of water. Consult the dealer from whom you purchased the unit or special installer. I Install the unit securely in a place which can bear the weight of the unit. When installed in an insufficient strong place, the unit could fall causing injury. I Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Incomplete connecting and fixing could cause a fire. I Do not use intermediate connection of the power cord or the extension cord and do not connect many devices to one AC outlet. It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc. I Check that the refrigerant gas does not leak after installation has completed. If refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated. I Perform the installation securely referring to the installation manual. Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or leakage of water. I Perform electrical work according to the installation manual and be sure to use an exclusive circuit. If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock. I Attach the electrical part cover to the indoor unit and the service panel to the outdoor unit securely. If the electrical part cover in the indoor unit and/ or the service panel in the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc. I Be sure to use the part provided or specified parts for the installation work. The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc. I Be sure to cut off the main power in case of setting up the indoor electronic control P.C. board or wiring works.
